The C++ Provider Factory Function

Once the class is written, all that is left is to provide a factory function that the CIMOM uses to load the provider. A macro is provided to make this very easy. If your C++ class is called MyInstanceProvider, simply put this line in your file:
OW_PROVIDERFACTORY(MyInstanceProvider, myinstprov);
The first argument is the C++ class name. The second argument is the identifier that the provider will be known as in MOF.
